Preoperative CT three-dimensional reconstruction guides single-incision minimally invasive esophagectomy with retrosternal route selection: a prospective cohort study.
Article in BMC surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe optimal reconstruction route following esophagectomy remains controversial, with limited objective criteria for route selection. This study investigated whether preoperative CT three-dimensional reconstruction can guide surgical route selection in single-incision minimally invasive esophagectomy (SIMIE) with retrosternal reconstruction.
methodsWe conducted a prospective analysis of 111 consecutive patients with esophageal cancer who underwent SIMIE with retrosternal route reconstruction between January 2024 and October 2025. Preoperative CT three-dimensional reconstruction measured both retrosternal reconstruction (RR) and posterior mediastinal reconstruction (PR) route lengths from esophagus at thyroid cartilage level to gastroduodenal artery. Primary outcomes included perioperative complications, particularly anastomotic leakage rates.
resultsMean RR route length was 293.3 ± 19.54 mm, significantly shorter than PR route length (315.4 ± 19.13 mm, difference 22.1 mm, p < 0.001). All patients completed SIMIE-RR successfully with mean operative time 209.5 ± 25.7 min, blood loss 65.5 ± 10.3 mL, and hospital stay 6.0 ± 1.0 days. Anastomotic leakage occurred in 2 patients (1.8%), both having longer RR than PR routes on preoperative measurements. BMI showed a strong positive correlation with RR route length (r = 0.6671, p < 0.0001), while other patient characteristics showed no significant correlations. Total lymph node harvest achieved 34 ± 10.2 nodes.
conclusionsPreoperative CT three-dimensional reconstruction effectively guides optimal route selection in SIMIE esophagectomy through objective pathway measurements. When RR route length exceeds PR length, particularly in patients with higher BMI, posterior mediastinal reconstruction may be preferable to reduce anastomotic complications.
